His name in the Spanish version is a play on the English word "barrel".

"Riccio" is an Italian word that can mean "hedgehog" (in reference to his spiky hair), "chestnut husk" (in reference to his barrel "shell"), "urchin" (as in a mischievous child or a street child from a poor neighborhood), or "sea urchin" (in reference to both his spiky hair and the "shell" that is his barrel).

"Toni", his Dutch name, may be a play on the Dutch word for barrel (ton).
